Mistress Mandy loves to experiment with all kinds of things. Today she wanted to try a chastity device. She wanted to make a guy wear it so she had fun turning this guy on. He was sure she wanted to fuck him but he was wrong. She only wanted to humiliate him and she did so. She had him wear it and then she teased him and watched how he got hurt as he got a hard-on. He had to beg her to remove it as she was the one with the key.
